  "title": "btrfs: fix double free in create_space_info() error path",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  btrfs: fix double free in create_space_info() error path  When kobject_init_and_add() fails, the call chain is:  create_space_info() -\u003E btrfs_sysfs_add_space_info_type() -\u003E kobject_init_and_add() -\u003E failure -\u003E kobject_put(\u0026space_info-\u003Ekobj) -\u003E space_info_release() -\u003E kfree(space_info)  Then control returns to create_space_info():  btrfs_sysfs_add_space_info_type() returns error -\u003E goto out_free -\u003E kfree(space_info)  This causes a double free.  Keep the direct kfree(space_info) for the earlier failure path, but after btrfs_sysfs_add_space_info_type() has called kobject_put(), let the kobject release callback handle the cleanup.",
